Connector terminal

Abstract

The connector terminal includes a first connector terminal and a second connector terminal to be fit into the first connector terminal, the first connector terminal including a flat spring making contact with a certain area of the second connector terminal, the certain area including a free end of the second connector terminal, and a terminal body including a pair of sidewalls between which the flat spring is disposed, the second connector terminal being formed in the certain area with two or more first projections each extending in a first direction in which the second connector terminal is fit into the first connector terminal, at least two first projections among the first projections making contact with the flat spring between the sidewalls.

What is claimed is: 
     
       1. A connector terminal including a first connector terminal and a second connector terminal to be fit into said first connector terminal,
 said first connector terminal including: 
 a flat spring making contact with a certain area of said second connector terminal, said certain area including a free end of said second connector terminal; and 
 a terminal body including a pair of sidewalls between which said flat spring is disposed, 
 said second connector terminal having a rectangular cross-section, 
 said second connector terminal including three or more first projections in said certain area on one of two surfaces thereof facing each other, said three or more first projections each extending in a first direction in which said second connector terminal is fit into said first connector terminal, 
 at least two first projections among said three or more first projections making contact with said flat spring between said sidewalls. 
 
     
     
       2. The connector terminal as set forth in  claim 1 , wherein said terminal body includes a ceiling portion and a floor portion each connecting said sidewalls to each other,
 said second connector terminal including in said certain area at least one second projection making contact with said ceiling portion and extending in said first direction, said second projection being formed on the other surface of said two surfaces. 
 
     
     
       3. The connector terminal as set forth in  claim 1 , wherein each of said first projections has an arcuate cross-section in a direction perpendicular to said first direction. 
     
     
       4. The connector terminal as set forth in  claim 1 , wherein said first projections are formed by pressing. 
     
     
       5. The connector terminal as set forth in  claim 1 , wherein a distance between said at least two first projections is equal to a distance between said certain area and one of said sidewalls, the latter distance being to be measured when said certain area is disposed at a center of said flat spring. 
     
     
       6. The connector terminal as set forth in  claim 1 , wherein a distance between said three or more first projections located adjacent to each other being equal to each other. 
     
     
       7. The connector terminal as set forth in  claim 1 , wherein each of said three or more first projections disposed at opposite ends in a width-wise direction of said second connector terminal has an inclined surface facing outwardly. 
     
     
       8. The connector terminal as set forth in  claim 1 , wherein said three or more first projections disposed at opposite ends in a width-wise direction of said second connector terminal are arranged to be located not to make contact with said flat spring even if said second connector terminal moves relative to said flat spring in a width-wise direction thereof. 
     
     
       9. The connector terminal as set forth in  claim 1 , wherein said flat spring includes an expanded portion making contact with said at least two first projections. 
     
     
       10. The connector terminal as set forth in  claim 9 , wherein said flat spring includes a central area expanding in an arcuate form, said expanded portion being formed in said central area. 
     
     
       11. The connector terminal as set forth in  claim 9 , wherein said flat spring includes a plurality of expanded portions making contact with said at least two first projections, said expanded portions being arranged in a width-wise direction of said flat spring. 
     
     
       12. The connector terminal as set forth in  claim 11 , wherein each of said expanded portions makes contact with said at least two first projections. 
     
     
       13. The connector terminal as set forth in  claim 12 , wherein a distance between said at least two first projections is equal to both a distance between said certain area and one of said sidewalls and a distance between said certain area and the other of said sidewalls, the last two distances being to be measured when said certain area is disposed at a center of said flat spring.
